Article Preview

Material constitutive model for metal machining is very difficult to obtain and establish accurately by conventional tension and compression tests. The dynamic mechanical properties and material model during machining aluminum 7050-T7451 are studied by means of orthogonal machining experiments (including quick-stop experiment, cutting force and cutting temperature measurements). Compare with compression tests (SHPB), the established material model with large strain (0.8~1.9) and high strain rate (0.45×105~1.89×105) in this paper is more valid and reliability in simulation and analyzing machining process.
